能率良く作業を行なうことができる。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for producing an integrally molded skin sheet that is applied to, for example, vehicle seats such as automobiles and furniture such as chairs. [Prior art] A skin-integrated sheet, which is made by bonding the skin to the surface of the pad (cover material), has design advantages and high durability, such as the fact that it does not wrinkle easily even after repeated use. It tends to be used frequently. Conventionally, in manufacturing this type of sheet, a mold 1 for molding the skin is used, as shown in FIG. 4, for example. In this conventional method, the seat portion 3 of the pad 2 is formed into a predetermined shape in advance.
At the same time, an adhesive 4 is applied to the mold 1 and the pad 2, and a skin 5, which has been previously sewn into a bag shape, is set with the front and back sides reversed. Thereafter, by pressing the seat surface 3 of the pad 2 against the mold 1, the seat surface skin 5 is molded and bonded to the seat surface 3 of the pad 2 via the adhesive 4. [Problems to be Solved by the Invention] In the conventional method described above, the seat skin 5 can be easily molded and bonded using the mold 1, but the side skin 6 is set with the front and back sides reversed. It is difficult to simultaneously form and adhere them to the side surface of the pad 3 using the mold 1. Further, as shown in FIG. 5, if the skin 5 is set in a bag-like manner on the inner surface of the container-shaped mold 1' without being turned over, the skin 5 can be molded and bonded from the seat surface 3 to the side surface 7 of the pad. It might be possible. However, in this case,
It is difficult to reliably hold the skin 5 in a predetermined position within the mold 1', and the shape of the pad 2 also makes it impossible to insert the pad 2 into the mold 1'. Therefore, an object of the present invention is to be able to correctly form and adhere the skin to predetermined positions ranging from the seat surface to the side surface of the pad;
An object of the present invention is to provide a method for manufacturing an integrally molded skin sheet with good workability. [Means for Solving the Problems] In order to achieve the above object, the manufacturing method developed by the present inventor is a method for attaching a skin to a pad having a seat surface portion and a side surface portion, the method comprising: A breathable skin that has been sewn in advance is placed on a first mold having a presser surface of a shape corresponding to the shape of the mold, with the breathable skin turned inside out, and a heat-melt adhesive film is overlaid on top of this skin. The adhesive film and the skin are adsorbed and shaped together by negative pressure from the inside of the first mold, and the seating surface of the pad is pressed from above the adhesive film, thereby forming a bond between the first mold and the pad. The seat surface skin and the adhesive film are sandwiched between the seat surface part, and then the side surface skin and the adhesive film are placed along the side surface of the pad, and a second mold is used to separate the side surface skin and the adhesive film. The adhesive film is heated while being pressed against the side surface of the pad, thereby integrally adhering the skin to the seat surface and side surface of the pad. [Operation] In the above manufacturing method, when setting the side surface skin and a part of the adhesive film along the side surface of the pad, the seat surface skin and the adhesive sheet are placed between the first mold and the seat surface of the pad. Since the portion corresponding to the seat surface of the pad is held in a predetermined shape and is prevented from moving, the side surface skin, which has been sewn into a bag shape, can be placed in the correct covering position along the side surface of the pad. Not only can it be easily turned over, but also a portion of the adhesive sheet can be correctly set in a predetermined position between the side surface skin and the pad side surface. In this state, the second
The first mold presses the side surface skin, and the first mold presses the seat surface skin while heating it to the melting temperature of the adhesive film, making it possible to integrally mold and bond the skin at predetermined positions spanning from the seat surface to the side surface. . [Embodiment W] An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. The pad 10 used in the vehicle seat shown in FIG. 2 is previously formed into a predetermined shape by a well-known manufacturing method. In the pad 1o of this embodiment, an integrally molded product of urethane foam is used as -PI. Preferably, it is an air permeable open cell foam. However, the material of the pad 10 is not limited to urethane foam; for example, breathable molded cotton made by binding the intertwining points of synthetic resin cotton fibers with a urethane binder may be used. The illustrated pad 10 has a seat portion 11, that is, a portion that supports the body pressure of the seated person, and a side surface portion 12 located around the entire circumference of the seat portion 11. This pad 1o is
Used as cushions for the seat or backrest of automobile seats. On the back side (upper side in the figure) of the pad 1o, there is a press support member 1 used in the press process described later.
3 is provided. The skin 15 includes a seat surface skin 16 that covers the seat surface 11 of the pad 10 and a side surface skin 17 that covers the side surface 12 of the pad 10.
These are sewn together in advance into a bag shape to match the shape of the covering, and are made of a breathable material such as woven fabric. A seam allowance 18 connecting the seat skin 16 and the side skin 17 faces toward the front side when the skin 15 is turned over. The heat-melting adhesive film 20 is attached to the seat portion 11 of the pad 10.
The material has a width sufficient to cover the side surface 12 from the outside, and has substantially no adhesive strength at room temperature, but can bond the pad 10 and the outer skin 15 by melting when exposed to high temperatures. used. Before melting, film 20 is substantially non-porous. The first mold 25 for molding the skin has a pressing surface 26 corresponding to the shape of the seat portion 11 of the pad on the top side in the figure. This mold 25 has a hollow shape with an air chamber 27 therein, and is provided with a large number of holes 28 (only the minus part is shown) that communicates the surface side of the pressing surface 26 with the inside of the air chamber 27. Furthermore,
A connection port 30.31 connected to the air chamber 27 is connected to a negative pressure suction means 32 using a vacuum pump or the like, and a steam supply means 33 for generating high-temperature water vapor. The second mold 35 shown in FIG. 3 has a pressing surface 36 corresponding to the shape of the side surface 12 of the pad 10. An air chamber 37 is also provided inside the second mold 35, and
A hole 38 (only a portion is shown) is provided to communicate the surface side of the holding surface 36 and the inside of the air chamber 37. A steam supply means 33 is connected to a connection port 40 connected to the air chamber 37 . This second mold 35 is divided into a plurality of pieces in the circumferential direction of the pad 10 as necessary. Next, a process of molding and adhering the pad 10 and the skin 15 using the above-mentioned apparatus will be described. As shown in FIG. 1, the skin 1 is sewn into a bag shape in advance on the first mold 25.
Cover with 5 upside down. Further, an adhesive film 20 is placed thereon. Thereafter, the negative pressure generated by the suction means 32 is applied to the air chamber 2.
7, the adhesive film 20 is sucked toward the pressing surface 26 through the breathable skin 15. The suctioned adhesive film 20 is adsorbed together with the skin 15 at a predetermined position on the pressing surface 26 while maintaining a predetermined shape, so that so-called vacuum forming is performed. While maintaining the above-mentioned shape-retaining state, the seat portion 11 of the pad 10 is placed on the adhesive film 20 as shown in FIG. While pressing it against the mold 25, the suction by the suction means 32 is released while maintaining this pressed state. Next, by turning the outer skin 15 over so that it is in a normal covering state, the side surface skin 17 is aligned with the pad side surface 12. By inverting the skin 15 in this way, a portion of the adhesive film 20 is attached to the side surface 12.
and the side surface skin 17. At the time of this set, the seat surface skin 16 and the adhesive film 2 are
Since the portion corresponding to the seat surface of 0 is in a shape-retaining state sandwiched between the seat surface portion 11 of the pad and the mold 25, it is possible to prevent the side surface skin 17 and the adhesive film 20 from shifting from their normal positions.
The adhesive film 20 does not have adhesive strength at room temperature, so it does not become sticky during setting and is easy to work with. By pressing the second mold 35 from above the side surface skin 17 toward the side surface 12 of the pad, the side surface skin 17 and adhesive film are formed between the second mold 35 and the pad side surface 12. 20. Through the above series of steps, the skin 15 and the adhesive film 20 are placed in a predetermined position between the mold 25.35 and the pad 10.
is reliably maintained in its molded state. If necessary, the side surface skin 17 may be vacuum-formed into a predetermined shape by applying negative pressure to the air chamber 37 of the second mold 35. Next, the steam supply means 33 blows high-temperature steam at a temperature sufficient to melt the adhesive film 20 into the air chambers 27, 37 of the mold 25.35. The blown steam flows through the holes 28, 38 to the breathable skin 15, so that the adhesive film 20 melts and the skin 15 and pad 10 are bonded together. After the pad 10 and the skin 15 have been molded and bonded in this way, the suction means 32 is operated again to reduce the pressure in the air chambers 27, 37 and remove water droplets adhering to the skin 15. The product after drying (skin integrally molded sheet) is mold 25.
．． Removed from 35. [Effects of the Invention] According to the present invention, the skin can be properly adhered to predetermined positions ranging from the seat surface to the side surface of the pad, and the work can be performed efficiently.
